In an electric power system, automatic generation control (AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power grid requires that generation and load closely balance moment by moment, frequent adjustments to the output of generators are necessary.
Conceptually, the Organic Rankine Cycle is similar to a Steam Rankine Cycle in that it is based on the vaporization of a high pressure liquid which is in turn expanded to a lower pressure thus releasing mechanical work. The cycle is closed by condensing the low pressure vapor and pumping it back to the high pressure.

Dec 25, 1984 · A once-through steam generator has both radiant and convection sections. The flue gases discharged from the convection section are passed through a wet scrubber to remove both sulfur oxides (SO x) and particulate matter. The feedwater to the convection section has its temperature controlled by the temperature of the flue gases discharged from the convection section, reducing the temperature of the feedwater by the use of a feedwater exchanger, as the convection section progressively fouls
Apr 24, 2017 · Steam generators are used to harness energy liberated as heat in a wide variety of processes and convert it into a form which is more useful, such as mechanical and electrical energy. The heat used is typically produced intentionally for the production of electricity or is captured as a byproduct of some other industrial process.

Steam boilers seem to operate efficiently with good steam quality when subjected to a steady steam demand at a rate matching the output of a boiler. Consequently, when a steam system valve opens quickly, a rapid steam load demand occurs, and the boiler will depressurize. When insufficient steam is available, depressurization occurs in seconds.
A waste heat recovery unit is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency.
